If the wheel is subjected to a normal force of p = 2.3 kn , determine the average shear stress developed in the pin. neglect friction between the inner scaffold puller leg and the tube used on the wheel. express your answer to three significant figures and include the appropriate units.

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
